Learn How to Swallowstail Mate: Mate in 1
This puzzle is a classic swallowstail mate pattern in a middlegame setting, where the attacking queen delivers a direct checkmate on a vulnerable king. The key idea is that the king has no safe flight squares because its own pieces and pawns block escape routes, while the checking piece controls the critical square. Even though Black is materially ahead, king safety overrides everything when the mating net is already complete.
